Extend Active Directory Schema - Windows Server 2019

Question

Hello,

I need to extend my AD Schema on Windows Server 2019.
I need to add a new attribute for users.

How do it correctly?

Answer 1

I did this a number of years ago following this article on TechNet:
https://social.technet.microsoft.com/wiki/contents/articles/51121.active-directory-schema-update-and-custom-attribute.aspx

Amongst the particular roles of some Domain Controllers there is the Schema Master, which is what you need to identify, switch to a writeable mode (it's set as read-only to avoid mistakes). Great care should be taken due to the potential for messing it up. I never had the luxury of a test labl, but that would be idea.
The article is fairly long, so read it through a couple of times, the examples were helpful to me).

Hi @drClays

The screenshots look ok, so not sure why it's not working. Have a look at this article on how to check if the new aux is shown in structure view and new attribute listed - https://nettools.net/schema-class-browser/

Just one point, as there is only one attribute in your aux class, is the aux class required and maybe just add the attribute to the user class.
